I’m not quite a C programmer and I’m going to interview a guy with 3 years experience in C in linux. In his CV, he says he is quite experienced with C programming.

So my question is if you are going to interview this “C linux” guy, what question or questions would you ask to make sure that this guy is competent? By the way,
I expect you give me the answer as well :-).

Thanks in advance.

    If the candidate really knows his stuff (C Linux programming) he’ll catch you pretty quickly, but anyway, here are a few pointers to topics you should investigate to prepare questions:

    • POSIX concepts
    • Standard C library (libc), ANSI C
    • Debugging and profiling tools: gdb,
      valgrind, strace, etc
    • Linux/UNIX system calls: sbrk,mmap,fork,etc
    • Threading
    • (Insert your favorite pointer question here)
    • The GNU toolchain: gcc,ld,as,automake,autoconf, etc.
    • Classic Linux utility C/C++
      libraries: glib,qt, etc.
